The new Sangoma W400 GSM boards are now available again for ordering. Our initial production proved to be too small for demand!
As a reminder, the Sangoma W400 is a modular 4-port GSM board that is compatible with Asterisk. It supports quad band GSM for worldwide deployments. A unique feature is access to SIM cards from the front bracket for easier management.
Typical use cases are for IP-PBXs establishing mobile to mobile calls and to provide bulk SMS.
